TALLMADGE, Ohio (AP) — Forensic anthropologists from Mercyhurst University in Erie, Pa., are examining the remains of a woman and her 5-year-old son to help northeast Ohio authorities determine how the pair died.

Police have said it's unclear when and how 31-year-old Wendy Ralston and her son, Peyton, died. The decomposed remains were found last weekend in woods behind their home in Tallmadge, about 25 miles south of Cleveland.

Police are investigating the deaths as homicides and have said they don't have a suspect.

An investigator's report indicated the remains appeared to be wrapped in a sheet and a bed comforter when Ralston's mother found them while visiting the home.
